I have, therefore, provided the flange percolator showing it tipped to pouring position, 3 substantially smaller than the opening 28 and with parts broken away and other parts shown with its internal diameter slightly smaller than 35 in section to illustrate the coaction of the cover the external diameter of the bead 24 so that the with the percolator cup during the pouring opcover 36 has to be forced over the bead when eration.

Thus the cover 30 must be for water or the like and has therein a percolaforced into position and is not easily displaced tor tube I2, upwardly through which the water from the percolator cup 43 and the container Ill. is percolated because of energization of a heating As shown in Figures 2 and 4, when the perelement in the percolator in the ordinary mancolator is tipped to pouring position, the upper 5 part of the flange 34 will engage under the bead 24 to prevent the cover from falling off. In Figure 4, it will be noticed that there is a space 1) between the flange 34 and the bead 24 at the lower side of the figure. At the top side of the figure, however, the flange 34 is behind the bead 24 and in fact is illustrated as merging therebehind about one-third way up the figure.

In replacing or removing the cover 30, the parts would assume the position shown in Figure 4 and then when the cover is forced on or off, the flange 34 squeezes the bead 24 and actually distorts it to nearly take up the space b while the flange 34 snaps on or oif the bead 24. It will be noted that the flange 34 is somewhat-flared (see Figure 5) to facilitate forcing of the flange over the bead when the cover is being placed in position.

The cover 30, of course, has the ordinary glass spreader 3| for the water which is percolated from the tube [2 to impinge against.

1 The cover 30,'of course, is loose relative to the opening 28 so that any unevenness in the contour of the opening will not affect the operation of thedevice and is also somewhat loose relative to the cup I8, but nevertheless will not fall therefrom as clearly illustrated in Figures 2 and 4. Even though the percolator A is tipped past horizontal, the'bead 24 will retain the cover 30 in position and even if the cover slips relative to the bead it cannot come off of its own weight because of the flange 34 being smaller in diameter than thebead 24. To remove the cover, force has to be applied to it with the cover arranged at a slight angle relative to the bead 24, as clearly shown in Figure 3.

Some changes may be made in the construction and arrangement of the parts of my device without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims, any modified forms of structure or use of mechanical equivalents, which may be reasonably included within their scope.

I claim as my invention:

1. In a percolator construction, a moulded container having an opening in the upper end thereof, a percolator cup therein having a peripheral bead at its upper end and a cover for the opening in the upper end of said container, said cover having a downwardly projecting flange fitted over said bead and having its lower edge contracted to a slightly smaller internal diameter than the external diameter of said bead whereby the cover is retained by said bead when said container is tipped to pouring position.

2. In a percolator construction, a moulded container having an opening in the upper end thereof, a percolator cup therein having a peripheral bead at its upper end and a cover for the opening in the upper end of said container, said cover having a downwardly projecting flange flared outwardly at its lower end and fitted over said bead and having its lower edge contracted to a slightly smaller internal diameter than the external diameter of said bead whereby the cover is retained by said bead when said container is tipped to pouring position.

3. In a percolator construction, a moulded com 3 tainer, a percolator cup therein and a cover for said container and fitting loosely relative thereto, said percolator cup having an annular bead at its upper end and said cover having a flange to engage under said annular bead when said container and said percolator cup are tipped to pouring position to prevent falling of said cover therefrom.

4. In a percolator construction, a moulded container, a percolator cup therein and a cover for said container and fitting loosely relative thereto, said percolator cup having a peripheral bead at its upper end, said cover having a flange normally positioned under said peripheral bead and removable therefrom only by forcing said flange up over said bead.
